Answer :
To hypothesize that autism is a quantitative trait normally distributed in the population.
Hypothesis that autism is a quantitative trait normally distributed in the population is actually showing the assumption that we can calculate the level of autism in the population in numbers as well as it is present in everyone at some level just like weight.
There are two types of data:
• Quantitative: Any information that can be counted is referred to as quantitative data and is given a numerical value. You can find out “how many,” “how much,” or “how often” using quantitative variables.
• Qualitative: Qualitative information is descriptive in character and communicated verbally as opposed to numerically.
Hence, here they are assuming that we can measure the level of autism in the population.
